ing is a description, reference being -had to' the accompanying drawings and to the let,- ters and figures of reference marked thereon. Our invention relates to an improvement I `in overseaming-machines yof that type particularly in which the overedge stitches are formed from two threads, carried, respectively, b a vertically-reciprocating eyepointed t cad-carrying needlel and a looper and in which the loops of needle-thread are taken'from the needle below the work-plate by a spreader 'or lodping-hook and carried out beyond the ed e ofthe throat-plate in such position as to ge entered above the material by the thread-carrying looper, which thread-carrying' looper resents its thread in such position that t e lneedle will pass through loops of looper-thread, thus making an overedge seam suitable for ornamenting edging or for uniting edges of superpose pieces of material.v

The object of the present invention is to provide a novel construction of overseamingmachine whidh is adapted to run at hi h speed and which shall be strong anddurab e.

The invention consists in the various details of constructions and arrangements of parts, all as hereinafter described, and referred to in the appended claims.

The invention is illustrated lin the accompanying drawings, in which- Figure 1 is a side elevation of a sewing-machine constructed in accordance with my invention. Fi 2 is a -skeletonized view of the rear part of t e machine, showing the mechanism for operatin the looper and thepulloffs and take-ups gor the needle and looper threads, respectively. Fig. 3 is a top'plan view of Fig. 2. yFig 4 1s a cross-section taken through the bed of the machine looking-toward the head of the machine and showing the trimmer and feed'mechanisms. Fig. 5 is a plan View of Fig. 4. Fig. 6 is u.

rear view of the machine, illustrating particularly the mechanism for shifting the needle-bar gate or frame. Fi 7 is a planview of the same, the frame oft e machine being removed and the forward part being shown in section. Figs. 8 and 9 are detail enlar ed views, showin the looping-hook or sprea eroperating mec anism In various positions and.

the corresponding positions of the needle and looper. Fig. 10 is a side view, artly in section, of the feed-dog and its a justingscrew. Fig. 11 is a detached View, partly in l section, illustrating the trimmer mechanism.

Figs. -12 to 16, inclusive, represent the vari-V ous positions of the looper, spreader, and needle 1n the operation of forming the stitch,

Qwhich stitch applied to two superposed pieces of fabric is also illustrated 1n said figures. Fig. 17 is a detail Aperspective view of 4the presserfoot- Fig. 18 is a perspective view showing the presser-foot and gulde, the trimmer, and the fabric and needle in their proper relations. V

In general the shape of the machine is of the well-known Union Special type, the bedplate A, standard B, gooseneck C, needles ever D, needle-,bar E, needlebar-suppo'rting gate or frame F, as well as other customary parts, being of the usual construction.- The driving-shaft G carries on its outer end the belt-pulley H, to which power is applied, and through the usual eccentric-strap I motion is transmitted to the needle-lever D.

The stitch-forming elements of the machine comprise, as herein shown, a verticallyreciprocating thread carrying eye pointed. needle 1, which carries a thread down to the material and in its upward movement throws out a loop 2, which loop is seized by a spreader or looping-hook S and carried laterally to a point above the cloth-plate of the machine, where it is engaged by an oscillating looper L, mounted onfa shaft M, supported entirely above the cloth-plate of the machine, Whic shaft is oscillated to carry a loop of thread 3 thr'ough the needle-loop and into position to be engaged by the needle in its next descent, thus making the overedge stitch illustrated in Figs. 12 to 16 of the drawings.

The particular looper movement which we have preferred to adopt in this machine and which is shown by way of illustration is the invention of Lansing Onderdonk, one of the Referring now to the drawings for a showing of the looper mechanism, said looper L carries a thread 3, and atits upper end or shank is secured in a collar 4, clamped to the lower end of the shaft M, which is arranged at an inclination to the cloth plate and slightly o the vertical, passing, through openings in the head of the machine, which form bearings for it. At its upper end the looper-supporting shaft is fitted into a socket on the clamping head or block 5, provided at the forward end` with a ball-stud 6, over which loosely fits a head 7, to which one end of the pitman-rod 8 is attached. This pitman-rod8 at its opposite end is screwed into a socket on a head 9, fitting a ball-stud 10,

- carried upon the end ofthe verticalarm 1 1 of the bell-crank lever, pivoted at 12 to the machine-standard B. The horizontal arm 13 of said bell-crank lever carries a ball-stud 14, upon which is fitted a head 15, located upon the upper end of a connecting-rod 16, which embraces the eccentric '17 u on the drivin -shaft of the machine. In t e rotation o the driving-shaft the inclined shaft which supports the looper is oscillated, carrying the looper from a point in rear of and to one side the needle around in a curved path inclined to the cloth-plate through the needle-loop, which has been brou ht by the spreader or looping-hook up into t e path of said looper and around in front of the needle, so that the needle in its descent passes through the loop carried on the looper, thus making an overedge stitch.

The spreader or looping-hook is shown particularly in Figs. 8 and 9 and isprovided on its upper end with a hook-or beak 18, adapted to seize the loop of needle-thread. Its lower end or shank is clamped into the upper end of an arm 19, pivotally supported upon the. twocranks and 21, which in turn are su ported upon rocking shafts 22 23, journaled in bearings in a bracket 24, secured to the bed of the machine. The lower crankshaft has secured to it a crank-arm 25, provided with a ball-stud 26, over which is fitted the head 27 of the itman-rod 28, connected l at its Opposite en to the lower end of the needle-'lever extension D.

As shown in Fig. 8, the needle is just beginning its upward movement and the spreader its upward forward movement, while in Fig. 9 the spreader has reached the limit of its upward and'forward movement, the looper has passed into the needle-loop on the spreader, which latter is about to recede therefrom,and the needle is about to begin its descent.

The various progressive movements of the parts in forming the stitch are shown seriatim in Figs. 12 to 16 and will be readily understood without 'further description.

The feed-dog 29 is operated in the manner customary in Union Special machines-that is, it is a four-motion feed operated from a crank-pin on the end,of a driving-'shaft and from a rocking frame 30 in rear of the machine with a-cam 31 o`n the driving-shaft to give the rise and fall.

In machines of this. character it is desirable to crowd the goods tqward the needle before the stitching takes rplace to prevent puckering after the stitches have been passed through the fabric, and the feed-dog 29 is therefore inclined and so arranged that as it is lifted that part of it ahead of the needle will catch the goods first. To vary the inclination of the feed-dog, the following construction is provided: The block 32, to which the feed-dog is secured, is'pivoted on a screw-bolt 33, attached to the rocking `arm 34, said block beingprovided near its lower end with an internal socket 35 with a slot opening downwardly, and fitting in this socket 35, which is ball-shaped, is a ball 36 on the end of the rod 37, which projects to the rear of the machine and is provided with a suitable thumb-nut 38, said rod being screw-threaded, as at 39, and passing through la screw-threaded projection 40 on the rocking arm 34, so that by manipulation of the thumb-nut the feed-dogsupporting block may be swung on its pivot to vary the inclination of the feed-dog with respect to the line of the cloth-plate.

In a machine of this character it is desir- `able to provide a trimming device which shallact ahead of the stitch-forming mechanism to trim off the edges of the fabric or fab# rics to prepare the said edge for the reception of the stitches, and in the present machine the trimmer comprises an upper movable- "knife and a lower coperating Vstationary knife, which two knives when brought t0- gether having a shearing action upon the goods. Briefly, the trimmer is operated by a 4connecting-rod 41, embracing the ball-eccentric 42 on the driving-shaft and at its upper end having a b'all connection with the end of an arm 43, which'at its rear end is loosely sleeved on the rock-shaft 44, supported in bearing-lugs on the machine-frame. The

upper trimmer-knife 45 is supported adjacent to the needle upon a second arm 46, which at its 'rear end is' fixed to the rock-shaft 44. The forward end of the arm, which is loosely sleeved to the rock-shaft, is provided with shoulders 47, between which passes a pin 48, screw-threaded in a lug 49 on the trimmerknife-supporting arm 46, said pin having on its upper end a manipulating-handle 50 and on its lower end having'a head 51, adapted to engage the shoulders referred to. This pin is screw-threaded and so arranged that when the handle is moved to the right the pin 4shoulder 57.

will be screwed up slightly, and the head 51 on the lower end will bear against the lower edges of the shoulders, thus securely pinning the trimmer-knife-supporting arm to the other arm 43, which is loosely sleeved on, the rock-shaft 44, and to which motion is imparted from the main shaft, thus giving the up-and-down movement `to the trimmerknife. When the two arms are not pinned together, the trimmer knife-supporting arm 46 with the rock-shaft may be swung out of engagement with the lower knife, andas it is swung up said arms come in engagement with a cam or projection 52 on the cloth-plate 53, which forces the rock-shaft longitudinally in its bearings and keeps the trimmer-knife out of engagement with the needle-clamping collar 54. The rock-shaft is journaled in lugs 55 56, above referred to, and toward therighthand end of the machine is reduced in sizev Within the barrel or provided with an annular shoulder 57 just within the enlarged portion of the lug, and upon this reduced end 58 is placed a spring 59, engaging the head or The barrel or enlarged part 6() of the lug 56 is screw-threaded to receive a hollow bolt 61, having a thumb-screw 62 on the end and provided also witha set-nut, so

as to vary the tension of the spring. This spring keeps 'the rock-shaft with the upper rtrimmer-knife normally pressed up to the stationary trimmer-knife.` i

As herein shown, the mechanism for shifting the needle-head consistsof a lever 63, pivoted vupon a stud 64, projecting rearwardly fro the lug 65 beneath the gooseneck C of the machine. One arm of this lever 63 extends toward the head of the machine and is provided with a fork 66atv its forward end, which engages a fiat pin 67, supported in a head 68, fastened toa lug 69 on the needle-bar gate or frame. This flat pin is Vinclined so that as the forward end of the lever moves u or down ithas. a wedging action against t e inclined pin and oscillates the needle-bar gate or frame.

nected at its outer end with a treadle-arm 71, the lower end of which is of course placed within reach of the foot of the operator. Near its outer end this lever-arm has a head 72, through which projects a bolt 73, and an 'oppositcly-'extendingl bolt 74 is threaded The opposite f arm 70 of the lever 63'extends toward they right-hand end of the machine and is conv lever 63 has a member 79, which engages the forked end 8070i the pivoted cast-off plate or arm. 81 to vary the point at which the casting off of the looper-thread from the shoulders on the swinging fingers 82 takes place. This mechanism will be hereinaftermore fully described in connection with the device for controlling the looper-thread.

The present machine also includes novel take-ups and pull-offs, one for the needlethread and one for the looper-thread, and we will now describe the needle-thread pull-off and slack-controller, which forms the subject-matter of a separate application filed by Lansing Onderdonk on the 9th day of November, 1901, Serial No. 81,766, but which as it forms an important part of this machine is herein described, as is also the looper-thread take-up, which is, per se, the invention of Russel G. Woodward and is described and claimed in an application filed by him on the 9th day of November, 1901, Serial No. 81,769.

This take-u and pulloff devices should also be automatically adjusted as the needle-head is shifted in order tobring the url on the edge of the goods, and the speci c mechanism for accomplishing this result is the invention of the said Russel G. Woodward.

Y Referring now particularly to'Figs. 2 and 3 of the'drawings, we have attached to the head or block 5, in which the u per end of the looper-shaft M issecured, a p ate 83, projecting'forward toward the front of the machine into a 'ath betweena stationary but adjustable eye et 84 on the gooseneck C of the machine and another pivoted eyelet 85, which'has alink connection 86 with the needle-bar head or gate. The forward end of the `arm or late 83', which is on thell'oopersupporting lead, is rovided with an eye or opening 87,r throng which `the thread is guided between said two eyelets 84 85. From the pivoted e elet abovel referred to the thread is guide to another stationary eyelet 88-on the upper needle-bar lug, and from there to the eye of the needle in the usual way. The action of this needle-thread take-up is as follows: Assuming the needley to be in its raised osition and just aboutto start downward, the needle at that timel hais' passed into the needle-loop., As the loopermoves forward to carry its thread into position to be engaged bythe needle in its descent the forward end of the eyeleted arm which moves with the loo er-shaft passes beyond the pivoted eyelet a ove referred to, which pivoted eyelet is of course in o erative position on the machine and pull; off thread suiiicient for the needle to use up in its downward movement. When this amount has been pulled off, the looper ineanwhile receding, said pull-off arm 83 moves back toward its normalposition, and when theneedle begins to ascend the eyeleted pull-off beioo Athread is guided. 1n a gina to pass out of the plane of the stationary eyeiet on the gooseneck, and-therefore takes up the slack in the needle-thread caused by the ascent of said needle, thus enabling all the superfluous thread to be taken stitch to be properly drawn up. To-allow for an increase of the thread pulled off and also for an increase in the amount of slack controlled, not only may the eyelet 84 be adjustable, but also the eyelet 85; but to allow for an increase of the thread pulledod when it is desired to make a wider seam-that is, to stitch farther from the trimmed-od edge than in normal` position-the pivoted eyelet, above referred to, is provided, which, as shown, is pivoted, as at 89, and at its lower end is connected by the link 86 with the upper needle-bar lug. When the needle-bar gate or frame with the needle is shifted by means of the mechanism described to take a wider bite into the goods by means of this link connection, the upper end of the pivoted arm carrying the eyelet isswung toward the standard of the machine, and thus as the forward movement of thelooper takes place more thread wiil bepulled off than when the needle-bar gate is 1n the normal position shown in the drawings.

Referring alsor to "Figs: 2 and 3 and also to Figs. 6 and 7, we will now describe the looperthread take-up. Secured to the upper end of the upper arm 11 of the bell-crank lever hereinbefore referred to are two forwardlyprojecting fingers or arms 82, having shoulders 99, which arms extend betweentwo stationary eyelets 91 upon thel machine-frame, through which stationary eyelets the looperplane betweenA these fingers or arms is a .cast-off plate or cam 92,

ivoted, as shown, to the machine-frame and having its lower end engaging, through the forked arm 80 and projection 79, the mechanism which shiftsV the needle-head. As the two fingers or arms move forward they en- -gage the looper-thread, which extends between the 'stationary eyelets and pull oif from the spool thread until such time as the upper edge of the cast-off plate or cam forces the thread out of engagement with the shoulders on the hngers or arms, thus releasing the thread. This forward movement of the iingers or arms to pull off the thread from the spools takes place while the looper is movingl out of the needle-loop, so that when' the looper begins to return to move into the needle-loop it has sufficient slack thread supplied it to form the stitch. When the needle-head is shifted .to make a wider seam, the upper edge of the cast-ofi plate vor arm is swung downward, so that in the forward movement of the fingers or arms the thread will not be.cast off from the'shoulders as quickly as when the cast-off plate or arm is in normal position, and therefore more thread out and they esmas is supplied to the looper, thus allo for greater width of seam.

The presser-foot 93 on this machine is of novel construction and is covered in an application filed by us on the 23d day of July, 1902, Serial No. 116,613. The foot portion 94 is hinged to the presser-foot shank in the usual way and is depressedl by a spring 95, which bears on the front end and is attached to a screw 96, passing through an arm 97, projecting from the presser-foot shank. The tongue 93, over which the stitches are formed, does not partake ,of the rocking movement of the bottom or shoe .of the foot, but is rigidly attached by the screw 99 to the presser-foot shank. Upon the forward end of the presser-foot a hem-guide lOOis provided. it will be, seen that the forward spring-pressed end of the presser-foot coacts with the inclinedfeedidog and that in the operation of the machine stitches are formed over the tongue vand fed off the same in the feeding movement.

cured to the presser-foot, as shown clearly in Fig. 17, and is adjustable laterally by means of the set-screw `in the use of this particular hem-guide 100, secured to the presserfoot, the folded edge of the fabric to be overseamed will be guided by the vertical ed e thereof, while the part of the fabric to e trimmed off will project beyond the lower edge of the said edge-guide, and as the goods pass to the trimmer this outer edge will be trimmed ofii. This is clearly shown in Fig. 18. it will be understood, however, that so faras the invention is concerned we do not wish to be limited in all respects to the guide located upon the presser-foot, for while this is a convenient arrangement for certain kinds of worir we wish to cover upon this character of machine means for adjusting the needle-har and its needlelaterally .with respect to the line of feed of a guide located in front of the needle and located in advance of the space which is included between the eX- trernes of llateral adjustment of said needle.

0f course the guide might be made integral with the presser-foot, but, as herein shown, is separate therefrom, or it may be attached to anotherart of the machine, or it may be constructs like any of the well-known forms of hemmers, the object of the invention in this respect being, as above stated, to provide in connection with the adjustment of the needle latenally to regulate its bite into the fabric a guide for the edge of the hem fold, leaving the part to be trimmed off projecting beyond the line of the guide and needle in order that the edge may be properly prepared for the reception of the bindingstitches.

It will be understood that we do not .wish to limit ourselves to a special construction of lOO needle-bar-supporting gate or frame, as the needle may be supported 1n such a way as to have a swinging or pendulum movement; but

' combination with a needle, a needle-bar and 65 this is not deemed necessaryto be hereinillusi trated.

The matters herein lshown and described, but not claimed, but yet which are novel, form the subj ects-matter of other applications filed by us individually-for example` the looper-movement itself, iiled by Lansing Onderdonk November 9,1901, Serial No. 81,761, the precise mechanism shown for shifting the needle-bar gate or frame toward or away from the trimmer, filed by Russel G. I/VoodwardNovemberQ,1901,Seriall\lo. 81,771; the automatic means for varying the amount of thread pulled off to supply both 'the needle and looper, filed by Russel G. Woodward November 9, 1901, Serial No. 81,769; thefeeding mechanism per se, shown in patent issued Russel G. W'oodward, No. 802,789, October 24:, 1905, and possibly other features; but the machine herein shown, described, and claimed, including the particular combination and arrangement of the stitch-forming elements and various other combinations, are the joint invention of us two and have been jointly invented and combined byus; but the present machine represents what we think is a high development, growing out of a longseries of experiments, and some of the particular features, so far as construction is concerned, have been invented by us individually; but these particular features are simply shown herein as best examples of means for accomplishing the same ends which we accomplish by other mechanisms invented by us jointly, but which did not prove to be so I practical as those herein illustrated.

Various minor modifications and changes in the constructions of parts of this machine may be made without departing from the spirit of our invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
